. Grass Valley, in the county of Nevada and which is mounted a gearcase7, in which is crank 9 whereb State of. California, have invented newand useful Improvements in Dish-Washing Machines, of which the followingisa .pecification.

This invention relates to dish washing apparatus: I

The object of the present invention is to provide a simple, substantial,easily operated machine for the washing of dishes, etc. The inventionconsists of the parts and the construction and combination of parts ashereinafter more fully described and claimed, having reference to theaccompanyin drawings, in which-,

igure 1 is a vertical transverse section through the machine. Fig. 2 isa horizontal section through the machine.

In the illustrated embodiment of the invention 2 is a suitably shapedtank, shown as cylindrical inform and of suitable depth, having attachedto its bottom a substantial support or spider 3, the projecting ends ofwhich may be perforated, as at 1, to receive screws or other devices 5by which the tank may be connected to a board, table or other support.

one side of the tank 2 is formed a rectangular chamber 6 on the rearside of journaled a gear shaft 8 bearing a gear 9, which in turn mesheswith and drives a pinion 10 mounted on a transverse shaft 11, on theouter. end of which may be mounted, if desired, a pulley or drivingwheel, not shown, whereby the apparatus may be operated by mechanicalpower.

On the end? of the shaft 8 is secured a the machine may be op: eratedmanuall The shaft 11 projects into the rectangular chamber 6 and. isprovided with a packing gland 12 to prevent the leaking of water fromthe tank 2 when this is being used. On the inner end of the shaft 11 isa pinion 13 meshing with an annular crown gear 14. which is attached toupright arms 15 of a. spider or frame 16 rotatable about a central stud17 in the bottom of the cylinder 2. A wing screw 18 may be screwed intothe bearing 17 about which the upright arms 15 may revolve.

Dishes to be washed are placed in position in a perforated or openscreen basket 20 of suitable depth and diameter to fit within the tank 2and rest on the frame 16 and within the annular crown gear 14 which isrevolved by the pinion 13 when the gearing 9-11 is operated.

One of the peculiar and special features of the present invention is themeans whereby the water and soapy substance, which may be inserted inthe water, can be forcedwith great pressure and washing e-fiect againstthe dishes, this neans comprising i in the present instance a propellerwheel 21 which may be secured on the shaft 11 to rotate in the cylindertl and force the cleaning water, which is fed into the tank throu hbasket carrying the plates contained therein successively arund causesthe current of water produced by the revolving propeller 21 tothoroughly cleanse the dishes.

After the dishes have been. washed, or

during the operation, the'sediment and unclean water mav be drawn fromthe tank 2,

through a drain connection or pipe 23 located at one side and nearthe-bottom of :the tank 2. A lid or cover 24 is provided and fittable.

over the upper open end of the tank'2, so as to keep the steam withinthe tank, to

maintain the water at as high a temperature as desired during thewashing operation:

The'baslret 20, in which the dishes may be placed, may be filled withdishes before it is arranged in the tank 2, and after the dishes havebeen thoroughly washed by the impingem ent of water thrown by thepropeller 21, the basket with the dishes may then be lifted out and thedishes allowed to drain and rinsed with fresh water, if desired.

Having thus described my invention, what I claim and desire to secure byLetters a closed" bottom with
